A YouTube-on megszűnt a "random"lejátszás?

I have made 2 playlists of videos, but I can't find any way to set up

random playback, so it gets really boring and repetitive to listen to

the songs over and over always knowing what is coming up next. Is

there some way to randomize playback from playlists?

If not, how in the world can i suggest this addition be made to

youtube, I have been looking through the help section of youtube and

they seem so confident that EVERY thins ever possibly needed is

answered that I can't find any way to contact them directly about a

new question or suggestion.

thanks
